You know you're nasty when...

You stay the night at your relative's house and you wipe your biggest boogers on the freshly painted wall several times. When confronted about it, you lie and say, "Oh, I must have sneezed on the wall." You promise to clean the wall the next time you visit.

Instead of cleaning the wall, you avoid the offended wall and visit the bathroom where you then wipe a bloody booger out of reach of everyone else that could have done it.
